these are older pics... but it kinda gives you an idea.... mine produced 212whp and 218wtq with my exhaust on AP stg 2... so it is right where it should be... flows well and is quiet... unless y ou are into it..
and my tip was a weld on cause I bougth the $80 non polished muffler without the tip.. you get the normal polished ones with tip and you pay $220+
its called welding and minnesota... not all of us like to throw money at shiny stuff that no-one sees... perrin.. not sure what size... swapped it with eric grimm when he put his back to stock to sell
